Abstract: A cartridge detachably attachable to a main body of an image forming apparatus is provided. The cartridge includes a rotary member and a cartridge coupler. The cartridge coupler includes a transmission member coupled to a rotation axis of the rotary member, a receiving member connected to a set coupler provided in the main body for transmission of power, and a connection member connecting the transmission member and the receiving member together. The receiving member has an Oldham structure allowing movement relative to the transmission member in an axial direction. The receiving member is movable to a first position at which a rotation axis of the receiving member is misaligned with a rotation axis of the transmission member in an attachment or detachment direction, and to a second position at which the rotation axis of the receiving member is aligned with the rotation axis of the transmission member.

Abstract: An electrophotographic image forming apparatus includes a cartridge for forming a visible toner image. The cartridge includes a development chamber having a toner inlet through which toner is supplied into the development chamber, a development roller provided in the development chamber, and a supply roller provided in the development chamber that supplies toner to the development roller. The cartridge further includes a first toner transporting member that transports toner supplied through the toner inlet in an axial direction of the supply roller, and a toner supply guide that is disposed between the first toner transporting member and the supply roller and includes a slit which has a length in the axial direction and through which toner is dropped onto the supply roller. The toner supply guide is downwardly inclined in the axial direction.
